NAV-IGABLE VESSEL.

SPECIFICATION forming part of Letters Patent No. 307,438, dated November4, 1884.

Application filed August 1F, 1884.

To all whom, it may concern:

Beit known that I, RUFUs BAR'rLEr'r Corr DON, of Belfast, in the countyof Waldo, of the State of Maine, have invented a new and usefulImprovement in Navi gable Vessels; and I do hereby declare the same tobe described in the following specification and represented in theaccompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 alongitudinal section, and Fig. 3 a transverse section, of a part of thebow 0f a vessels hull, with its lumber-port provided with :my invention,the nature of which is defined in theV claim hereinafter set forth. Fig.4 is a front View of the port as open.

Vessels provided with lumber-ports at the bow usually have at the mouthof the port a simple rabbet extending around such to receive and supportthe door or closure of the port, such door or closure being held inplace by one or more turn buttons or bars extending across the portwithin the hold, and secured at the :middle of each to the door orclosure. In heavy or stormy weather such closures, covers, or doors areliable by the sea to be broken in or detached from the hull, greatly toits detriment, and impcriling the safety ofthe vessel. a

My invention is to support the port cover or closure at and across itsmiddle, as well as at its edges, and thereby render it more se cure andbetter capable of withstanding the shocks of the seas. .To this end Iform in the port at its middle, and to extend inward from the upper andlower paris of its rabbet, two l (No model.)

recesses to receive a strong cross-piece or cleat at its ends, suchcross-piece or cleat being bolted to the port cover or door. Theturnbutton or bar for holding the cover in place is at its middleconnected to the cleat.

In the drawings, A denotes the bow, and B the lumbenport, having at andaround its mouth the usual rabbet, a, to receive the door, cover, orclosure C. It also has leading ont and in rearof the rabbet, at itsupper and lower parts, the two recesses I) b, to receive the cross-pieceor cleat D, extending across the cover and iixed to it. This cleat atits end portions enters and rests within the recesses, and at its middleis connected by a line or other proper device, c, to the cross-bar E,used for holding the coverin place. The cleat not only greatlystrengthens the cover or door at its middle, but with the sockets orrecesses, for reception of it, the said cleat operates to there supportthe cover or door to great advantage to prevent it from being stove inby the seas in heavy weather.

I claim- In combination with the lumber-port and its door or cover ofthe hull of a navigable` vessel, the cleat or support-piece arrangedacross the cover at or near its middle, and the recesses for receptionof such cleat extending back from the rabbet of the mouth of the port,all being substantially as set forth.
